Darfur: UN estimates over 400,000 deaths, 2m displaced

Over the past two years, I've covered miles of news reports on Darfur and am still unable to understand why the African Union Mission in Darfur was never given the support it needed to function effectively. Report by the UN News Centre 21 Sep 2006 - Annan welcomes extension of African Union mission in Darfur:

In a statement issued by his spokesman, Mr Annan stressed that additional funding for the mission, known as AMIS, is urgently required for it to function effectively during its new mandate in a region where UN officials estimate over 400,000 people have lost their lives and some 2 million more have been driven from their homes in three years of fighting between the Sudanese Government, allied militias and rebel forces.

Note, the report states UN officials estimate over 400,000 deaths.
